Note: I rarely watch these videos in their entirety but the results of this one were surprisingly impressive enough to keep me glued to the end of my toilet seat for all six minutes (plus I have a stomach bug).
Remember The Backyard Scientist's 150MPH rocket knives? Well now's back and heating them up to 1,000 degrees to slice clean through 1) a plastic Coke bottle, 2) two steel cans of silly string, 3) a baguette, a two by four and a brick, and 4) a whole bunch of lighters. The lighters were cool (you know how I feel about fireballs, plus the flaming track afterwards reminded me of the fire trail left when Doc Brown's time-traveling DeLorean takes off) but I think the baguette and two by four and brick were the most impressive. I did not think it was going to be powerful enough to do that, but I was wrong. Never underestimate the power of a 1000-degree rocket knife, that's the message here. Now do your finger next, there's no way it'll cut through bone and you'll just need a Band-Aid after.
Keep going for the video.
Thanks to hairless, who once tried shaving with a 1,000-degree rocket knife and that's why he is the way he is now.
